This is not about just Fortran libraries. Imagine a reasonably big
program, like Netscape or Emacs, of which you usually just use a
subset of features. There can easily be many megabytes of code and
data in them you never actually use, or you don't _usually_ use
(like the people who use emacs like it was vi :). Without
overcommit, you need to allocate all that memory for the code, no
matter whether you end up using it or not. With overcommit, there is
no such problem.

And that's not all, either.

Hell, people, if overcommit was not useful, everybody wouldn't be
doing it.
